COMPUTING AND STAMPING SCALE.

Specification of Letters Patent.

Patented Mar. 28, 1916.

Application filed February 24, 1914. Serial No. 820.708.

To all whom it may concern:

Be it known that I, PINGKNEY Sn'rrm HARcRovE, a citizen of the United States, residing at 71 Fountain street, New Haven, in the county of New Haven and State of lonnecticut, have invented a new and useful Computing and Stamping Scale, of which the following is a specification.

My invention relates to a new and 1mproved computing and stamping scale, of the type wherein means are provided for accurately determining, recording and registering the weight of an object, as well as its price, or other desired data in connection therewith.

It is the object of my invention, among other things, character that will be composed of the fewest possible parts that are simple in design, readily assembled and will perform their functions in a quick and accurate manner.

To these and other ends, my invention consists in the computing and stamping scale, having certain details of construction, and combinations of parts, as will be hereinafter' described and more particularly pointed out in the claims.

Referring to the drawings, in which like numerals of reference designate like parts in the several figures, Figure 1 is an elevation of my improved device partly in section; Fig. 2 is a fragmentary end viewthereof; Fig. 3 is a view of the cylindrical ink pad with the stamps in contact therewith; Fig. 4

4 is a detail view of the screw mechanism for limiting the movement of the striking levers; Fig. 5 is a detail View of a portion of one of the striking levers and the disk with which it is connected; Fig. 6 is a fragmentary plan view of one of the striking levers; and Fig. 7 is a side elevation thereof.

In the practice of my lnvention I provide a case 1, within which the shaft 2 1s journaled in the bearings 3, at each end thereof. Fixed upon this shaft are the disks 4 having a plurality of teeth 5 in the outer edge thereof. These disks are provided with one or more apertures 6 therethrough and arranged so as to leave a portion 7 upon one side thereof that acts as a counter-weight to said disk. As shown herein this counter-weight is made integral with the disk, but it is apparent that a separate member can be attached thereto if desired, the weight of which will depend upon the needs of the scale for light or heavy weighing. This counter-weight to produce mechanism of this balances the weight of the object placed on the tray 8 which is secured upon the rods 9 that pass through the top of the case and are provided with a plurality of teeth 10 that engage the teeth 5 in the disk 4 and are supported at their lower ends in the bar 11 securedwithin the case. The tie bar 12 forms a rigld connection for the rods 9 at their lower ends.

Secured to the shaft 2 is a screw disk 13, within which are threaded a plurality of ad usting screws 14, which project radially from the periphery thereof and are provided with a V notch 15 in the heads thereof adjacent to the screw-driver slot 16.

One of the disks 4 is provided with a plurality of openings 17 therethrough and within each of which is pivoted the rear member 18 of the striking levers 19. The member 18 and the striking levers 19 are adjustably secured together by the screw 20, which passes through the slot 21 and has a nut 22 threaded thereon.

J ournaled between the arms 23 of the striking lever 19 is the stamp 24, having any legend formed thereon that may be desirable, and provided with a lug 25 upon its rear face, in which there is a slot 26.

An auxiliary lever 27 is connected with the stamp 24 by the pintle 28, which passes through the slot 26 and travels therethrough while the stamp is rotating upon its pivot mounting. This auxiliary lever is pivotally connected with one of the disks 4 by the extension lever 29 that is adjustably connected with auxiliary lever in substantially the same manner as the rear member 18 and striking lever 19 are secured together.

' Fixed to the shaft 2 is a cylindrical ink pad 30, against which the stamps rest when inactive, and from which they take sutficlent ink to make an imprint of the legend thereon upon the object placed upon the tray.

The striking levers are actuated by a push rod 31 that is supported in a lug 32 in the case 1, and having an impact point 33 thereon that enters the V wings 34 at the free end of the rear member 18. The push rod 31 is returned to its up position by the spring 35 which is secured at each end and pulls said rod upwardly. The down position of the rear member 18 and the'up position of the stamp 24 is limited by the screws 14, which provide means for a very fine relative adjustment of the position of said stamps. The wing portions 34 upon the rear members 18 insure the. positive en-' 19 must be provided so that the stamp 24 thereon will contact with the object on the tray through the opening and the rear member 18 with one of the adjusting screws 14 at one and the same time. I have, therefore, provided a plurality of said striking levers of varying lengths, only one of which is shown in Fig. 1 for the purpose of clearness, but an end View of all of them is shown in Fig. 2.

Forming part of the recording mechanlsm are the drums 36, 37, and 38, which are mounted upon the shafts 39, 40, and 41, all journaled in the case 1 and the bar 48. WVound upon the drum 37 is a roll of paper 42 and a printing ribbon 43, both of which pass over the screw disk 13, the former being wound-on the drum 38 and the latter upon the drum 36. Shafts 39 and 41 are provided with gears 44 and 45 which are connected by the gear 46 rotatable upon the shaft 47.

Movement is imparted to the ribbon 43 and paper 42 through the ratchet disk 49 fixed on the shaft 41 and a pawl 50 secured to the arm 51 integral with the push rod 31, so that during every downward'movement of the push rod 31, the pawl 50 passes one of the teeth upon the disk 49 and during its next upward movement imparts a rotarymovement thereto, and through it to the rolls 36 and 38.

Upon the underside of each of the wings 34 is a printing stamp 52 having a legend thereon containing the data desired to be recorded, which prints upon the paper 42, with the assistance of the ribbon 43, at the same time as the stamp 24.

There are minor changes and alterations that can be made within my invention, and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of the appended claims.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device of the character described, the combination with a body member; of a plurality of levers pivotally mounted therein; a platform; means for connecting said platform and levers whereby the movement of said platform will move said levers to a position determined by the extent of movement of said platform; and means for actuating said levers when in their latter posiplurality o'flevers pivotally extent of movement of tion whereby they will be brought into contact with the article upon said platform and imprint a legend thereon.

2. In a device of the character described, the combination with a body member; of a plurality of levers pivotally mounted therein; a platform; an operative connection between said platform and levers whereby the movement of said platform will move said levers to a position determined by the extent of movement of said'platform; means for actuating said levers when in their latter position whereby they will be brought into contact with the article upon said platform and imprint a legend thereon; and means connected with said levers whereby a legend similar to the one imprintedfon said article may be imprinted upon mechanism within said body member.

3. In a device of the character described, the combination with a; body member; of a mounted therein; a platform; a registering mechanism within said body member; means for connecting said platform and levers whereby the movement of said platform will move said levers to a position determined by the extent of movement of said platform; and means for actuating said levers when in their latter position, whereby they will be brought intocontact with the article upon said platform and said registermg mechanism and imprint a legend upon each.
